ben-sci-tools 0.0.5

useful python tools that I use to streamline my work.

Project Description

ben-science-tools (bst) is meant to contain tools that Ben uses to streamline some of his porcesses while working on computaional chemistry. The project currently has two main modules process_data which is used for log file or computaional chemistry output file processing and analysis, and input_file_maker which is used to generate file inputs for computational chemistry
